1 June 2021 - Professor Barry Dwolatzky South African-born engineer and entrepreneur is making a significant contribution in the fight against Covid-19. Athens, Ohio, and Potchefstroom, South Africa, seem to be worlds apart, but they do have some surprising similarities and connections. Athens is a small city in Americaâs Midwest. It has a tiny âdowntownâ area with a few shop-lined streets, some churches and modest historical buildings. It has more than its fair share of trendy food places, bars with live music and coffee shops. These serve the needs of its nomadic population of university students. Dominating the city is the largest campus of the Ohio University with an enrolment â in Athens â of about 22,000 students. The non-student population of Athens is about 5,000.
